The paper presents the design and simulation of a bi-directional multilevel converter with a synchronous half-bridge DC-DC converter for V2G applications. In the first stage, the single phase, three-level neutral point clamped (NPC) topology, and also a synchronous half-bridge dc-dc converter are selected, taking into account the minimum deviation of the output current, the size and weight of the output filter, the total output current harmonics deviations, and the minimum number of the component. In this sense, the modeling and simulation of the power converters selected are presented. In the second stage, the ancillary and measurement circuits with a corresponding model and simulation were designed. Finally, the simulation results were obtained with the required performance in the operation of the power converter in both ways. The main achievement of this research work is to allow the development prototype of the power converter for electric vehicles which accomplishes international standards.
